For example: 35ZWK2-J namely: Medium temperature basic type, output power is 35W per meter at 10 ℃, working voltage is 220V.

ZR45ZWK3-PF means: flame retardant medium temperature shielding protection type, output power of 45W per meter at 10 ℃, working voltage of 380V, with flame retardant, explosion-proof, protective performance.

Technical index of two-temperature self-limiting electric heating series:
1. Temperature range:

Maximum working temperature 105 ± 5 ℃;

The highest surface temperature is 135 ℃;

Maximum withstand temperature: 105 ℃ for modified polyolefin, 135 ℃ for flame retardant polyolefin, 180 ℃ for fluorinated polyolefin, 205 ℃ for perfluorinated material

2. Construction temperature: The lowest construction temperature is -40 ℃, the best construction temperature is above 0 ℃

3, thermal stability: 1000 on and off for 30 consecutive days, the cable's heat is maintained above 90%.

4. Bending radius: 12.7mm at 20 ° C and 35.0mm at -30 ° C

5. Insulation resistance: the cable length is 100m, and the room temperature is 20 ℃, 1000VDC is used to shake between the shielding layer and the conductive core for 1 minute, and the minimum insulation resistance is 1200MΩ.

6. Working voltage refers to 12, 24, 36, 48, 110, 220, 380 volts, etc., AC and DC dual-use, low-voltage products must not be applied under high-voltage conditions.


Application:
The medium temperature self-limiting electric tropical series is widely used in petroleum, chemical, steel, electric power and other industries for process pipelines, storage tanks with heat insulation and anti-freeze insulation, and its medium maintenance temperature range is 0 ~ 105 ℃

The basic electric heating belt is generally used in places without explosion-proof, anti-corrosion requirements, and low environmental humidity;

Protective electric heating belt is generally used in places without explosion-proof and anti-corrosion requirements, but with high ambient humidity;

Explosion-proof electric heating belt is generally used in places with explosion-proof, no anti-corrosion requirements, and low environmental humidity;

Explosion-proof protective electric heating belt is generally used in places with explosion-proof, no anti-corrosion requirements and high ambient humidity;

Explosion-proof and anti-corrosion electric heating belt is generally used in places with explosion-proof, anti-corrosion requirements and high ambient humidity

If the product is required to have flame resistance, you can choose the corresponding flame retardant series.
